Easy "Praetor Slayer" trophy

The "Praetor Slayer" trophy normally requires you to successfully complete the "Say Your Praetors" challenge in five different ways, with each one requiring you to kill a different Praetor. However, there is a glitch that allows you to easily get this trophy once you have discovered a method to kill any of the five. First, discover or look up any method to successfully complete the challenge. Then, start the challenge, and buff up your Baneslayer Angel any way desired so she can kill one of the other Praetors on the defense. Once the Praetor has been killed, display the menu, and select the "Restart Challenge" option. Choose a different Praetor, and kill it as before, then restart again. Repeat this process until you have killed each color of Praetor once. Then, restart the challenge again, and successfully complete it. When the win screen appears, you will get the "Praetor Slayer" trophy.
